Operation of Rollerbed TrailerThese 68,000#GVWR, Panel and Truss Rollerbed Trailers have a flat profile, with a Hydraulic NeckAssembly, a sliding tandem, 6” air unlocking deck rollers, and 11R/22.5 tires. The deck rollers are spacedapproximately 2 ft. apart. 3’ on the front deck portions.Hydraulic neck assemblyThe hydraulic neck is an articulating arm with a hinged upper coupler plate. It’s designed to be used inconjunction with the sliding tandem, ground level feature in its application. It is equipped with a selfcontained, 12 volt, DC hydraulic pump to supply lifting power in specific situations. The objective is to create amore favorable angle of delivery by setting the trailer down to the ground, or near the ground, at the rear. Thissystem is designed for use by articulating the arm while the tandem axles are locked in a forward position. Thissystem will lift 12,500# from the initial position with the trailer tandems at the rear most position. The systemwill lift more weight as the tandems are shifted forward which transfers more weight behind the tandems andoff the front of the trailer. The more you want to lift the farther forward you slide the tandems.Hydraulic neck operationThe self contained, 12 volt, DC hydraulic pump in this system has a push-pull cable control switch to powerthe system up and down and allow gravity movement. The system has 5 positions, 2 towards the frame, 2 awayfrom the frame and neutral. Two of the positions are power and two are gravity. The cable will activate themotor and pump when it is slid into one of the power positions.#1-All the way towards the operator will lift the front end up.#2-Mid way operator will gravity the fifth wheel to the ground when the tractor is removed from the trailer(never use #2 position, it will only allow air into the system).#3- The middle is neutral with a ball seat that is released by pushing the red button inside the handle.#4- Midway towards the frame and gravity will bring the front end down.#5- All the way toward the frame will power the front end down.NOTE: Recommend practice is to use #1 position to lift the trailer and #5 position to let the front end backdown. Hold the handle in the power position being used and immediately return to the handle to neutral themoment the desired travel I the front is achieved. Do not allow the handle to slide into the gravity positions. Donot allow the gravity positions to move the front end.Truck requirements for charging batteryThe trailer comes with a 12-volt battery as a power source for the hydraulic pump. A single post femaleelectrical receptacle has been supplied by the manufacturer for charging this battery. This receptacle is locatedon the front bolster near the 7-way receptacle and is wired to the battery for charging, while the trailer iscoupled to the truck. It is necessary to have the other end of this plug wired to the truck to charge this battery.This system requires power through a 30 AMP fuse in the fuse panel of the truck and minimum of a 6-gaugewire leading to the plug.Expanding the trailer (Expandables only)1.Remove the auxiliary air line from the storage fitting-located on the driver side at the front of the rearmain frame-and connect it to the open fitting on the forward air chamber. This should immediatelydisengage the frame index pins.2.Pull the truck forward until the holes in the inner frame and the index pins on the outer frame line upat the desired frame length.- 10 -

3.Remove the auxiliary air line from the air chamber and replace it on the storage fitting. When theauxiliary air line is removed, the frame index pins should engage. Sometimes it is necessary to roll thetruck back and forth, slightly, to align the pins.NOTE: Always make sure the index pins are locked before loading the trailer and/or moving the trailer toanother location.4.Follow the expanding procedures above when returning the trailer to the closed length.Unloading procedures1. Get trailer in position to unload.2. Unlock slider bogey lock located on the driver side front of the axles for positioning the bogey to thedesired location on the main frame of the trailer by depressing the air assist device. The slide bogey lockmechanism is a double action lever. When the air assist is activated it will apply pressure to themechanical lever that retracts the lock pins. The lock pins may not retract until they are unbound by theoperator using the tractor to roll the trailer back and forth, relieving the pressure against the locking pinsthereby allowing them to retract.NOTE: Allow the air assist and the tractor to do the work. If you manually pull the lever out too far youcould rack the lever mechanism.3. Raise rear bumper by opening the vented ball valve next to the roller unlock valve. This will raise therear safety bumper.4. Unstrap and store the rear strap at the back of the trailer (this is done because this strap is difficult tounstrap when the trailer is in the ground-level position).5. Get in truck and get shifter in reverse.6. Start backing up with a fair amount of speed. (This is very important because you cannot start theprocess from a dead stop, you must be rolling in reverse to start the procedure.) Pull the tractor handvalve down, this will lock the trailer axles in place, and you will be sliding the main frame of the trailerover and through the slider bogey.NOTE: When sliding the trailer into the ground level position, be sure to make this step a smooth, quickmotion.7. Apply the parking brake to the truck and trailer.8. Lock the slider bogey to the main frame at the desired position. (The desired position can be anywherealong the slider range of motion).9. Lift the front of the
